ABSTRACT:
A hydrostatic adjustment unit with a swash plate for adjusting the stroke of displacer pistons which are arranged in a rotating cylinder block is described. The displacer pistons each have a slider block which bears against a support face of the swash plate and is held in abutment by means of a slider block holder. The slider block-holder has a number of bores for receiving the slider blocks corresponding to the number of displacers. The slider block holder at the same time forms the rotor of a rotational speed signal transmitter for determining the rotational speed of the cylinder block.
